Is there such thing called a person?

In philosophy, the question of whether or not there is such a thing as a person is known as the problem of personal identity. There are two main theories of personal identity:

* The psychological continuity theory states that a person is the same person over time if and only if they have psychological continuity, such as memories, beliefs, and desires.

* The physical continuity theory states that a person is the same person over time if and only if they have physical continuity, such as the same body or brain.

There are arguments for and against both of these theories. Some philosophers argue that psychological continuity is more important than physical continuity, while others argue the opposite. Ultimately, the question of what constitutes a person is a philosophical one that has no easy answer.
